You can change these values via functions.php file located in theme folder.
You can access this file via WordPress dashboard as well. Just go to Appearance → Editor.

And change the line that says

<code>add_image_size( &#039;featured&#039;, 670, 300, true );</code>

Just change the second value to 350 or whatever height you want to use for featured image.

If you have already set featured images then you will have to use this plugin (http://wordpress.org/plugins/regenerate-thumbnails/) to regenerate featured images.
In case you are starting from scratch you shouldn’t worry about this part.
